I would hope the next iPod rev while including a scren covering the entire unit would also include bluetooth and WiFi. Unlike the current slated specs for the iPhone, wireless sync should come standard. The ability to surf the iTunes store and buy tracks would also be pretty cool, though for me not a big deal (since I personally still purchase my music on CD). Internet audio streaming and movie streaming would be a must, if for nothing else than to preview clips and trailers of what you might want to buy. Then of course this could mean wireless sync and transfer between iPod and AppleTV.

It goes without saying they should pick up the new 100GB 1.8" drives as a minimum for their higher end model. 100-200GB of flash RAM would be better, but I don't think that's realistic for a few years still.
